Abstract
Description
Technical Field
[0001] This utility model relates to the field of induction cooker technology, and in particular to a novel induction cooker with high efficiency and energy saving. Background Technology
[0002] An induction cooker is a kitchen appliance that uses the principle of electromagnetic induction to heat food. It is characterized by high efficiency, energy saving, safety, and convenience, and is widely used in home and commercial cooking scenarios. The induction cooker generates a high-frequency alternating magnetic field through an internal coil. When an iron pot is placed on the cooktop, the bottom of the pot cuts the magnetic lines of force to generate eddy currents. These eddy currents cause the pot to heat up, thereby heating the food.
[0003] In most conventional induction cookers, eddy currents are generated at the bottom of the cookware through a high-frequency alternating magnetic field during use. This process is inevitably accompanied by the diffusion of the electromagnetic field. Although the magnetic field is mainly concentrated at the bottom of the cookware, some magnetic lines of force will leak into the surrounding space. Furthermore, due to different usage conditions, such as the cookware being placed off-center or being too small, magnetic leakage will be increased. As a result of magnetic leakage, some magnetic lines of force do not effectively act on the cookware and escape into the surrounding space, leading to energy loss.
[0004] Therefore, a new type of induction cooker with high efficiency and energy saving is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a novel induction cooker with high efficiency and energy saving to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel induction cooker with high efficiency and energy saving, comprising a furnace body, a coil disposed in the furnace body, and a cooling fan, wherein an mounting ring is fixedly installed in the furnace body and is located outside the coil; the mounting ring is provided with an anti-magnetic leakage component for reducing coil magnetic leakage, the anti-magnetic leakage component comprising a silicon steel sheet and an insulating plate disposed in the mounting ring, the silicon steel sheet and the insulating plate being staggered and forming a superimposed layer, the superimposed layer having an air channel and an exhaust hole, and the air channel and the exhaust hole being connected.
[0007] Preferably, a limiting post is fixedly connected to the mounting ring, and a limiting hole adapted to the limiting post is provided on the superimposed layer.
[0008] Preferably, a mounting plate is fixedly connected to the mounting ring, a pull rod is slidably connected to the mounting plate, a limit plate is fixedly connected to the pull rod, and a spring is fixedly connected between the limit plate and the mounting plate.
[0009] Preferably, the mounting ring has an air inlet, which is connected to the air duct, and the air inlet is located at the top of the cooling fan.
[0010] Preferably, the furnace body is provided with heat dissipation vents and air circulation vents, and the air circulation vents are located at the bottom of the cooling fan.
[0011] Preferably, the top of the stove body is provided with a pot, and the outer side of the pot is provided with a heat insulation plate to prevent heat loss from the pot, and the heat insulation plate is attached to the edge of the pot opening.
[0012] Preferably, a fixing plate is fixedly connected to the heat insulation plate, the fixing plate is provided with fixing bolts, and the furnace body is provided with screw holes that are compatible with the fixing bolts.
[0013] The beneficial effects of this utility model are:
[0014] This invention incorporates an anti-magnetic leakage component, which allows the magnetic leakage generated by the coil during induction cooker use to be concentrated and guided onto the cookware by silicon steel sheets. This results in higher heating efficiency for the cookware and reduces energy consumption by preventing magnetic leakage, thus making the induction cooker more efficient and energy-saving. Furthermore, the staggered arrangement of the silicon steel sheets and insulating plate ensures insulation and stacking between the sheets, forming a more continuous magnetic circuit, increasing overall permeability, and enhancing magnetic field strength. This leads to better heating of the cookware and increases the resistance between the silicon steel sheets, reducing eddy current losses and preventing a decrease in permeability due to heat generated by eddy currents between the sheets.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0025] As shown in Figure 1 Figure 6As shown in the figure, a specific embodiment of this utility model provides an induction cooker with high efficiency and energy saving, including a furnace body 1, a coil 2 and a cooling fan 3 disposed in the furnace body 1. An installation ring 4 is fixedly installed in the furnace body 1, and the installation ring 4 is located outside the coil 2. The installation ring 4 is provided with an anti-magnetic leakage component for reducing magnetic leakage of the coil 2. By setting the anti-magnetic leakage component, the magnetic leakage phenomenon generated during the use of the induction cooker can be reduced, thereby reducing energy loss and making the induction cooker more energy-efficient. It also makes the generated magnetic leakage more concentrated at the bottom of the pot, thereby improving heating efficiency. The anti-magnetic leakage component includes a silicon steel sheet 5 and an insulating plate 6 disposed in the installation ring 4. The silicon steel sheet 5 and the insulating plate 6 are staggered and form a superimposed layer 7. The superimposed layer 7 is provided with an air channel 8 and an exhaust hole 9, and the air channel 8 and the exhaust hole 9 are connected.
[0026] like Figures 3 to 6 As shown, specifically, when the induction cooker is in use, a pot 18 is placed at the top of the cooker body 1. The coil 2 in the inner cavity of the cooker body 1 generates an alternating magnetic field. The alternating magnetic field generates eddy currents at the bottom of the pot, causing the pot 18 to heat up. During the process of generating the alternating magnetic field, magnetic leakage occurs, and some magnetic lines of force leak into the surrounding space. The reason for this magnetic leakage has been mentioned in the background technology. A limiting post 10 is fixedly connected to the mounting ring 4, and a limiting hole adapted to the limiting post 10 is provided on the superimposed layer 7. A mounting plate 11 is fixedly connected to the mounting ring 4, and a pull rod 12 is slidably connected to the mounting plate 11. A limiting plate 13 is fixedly connected to the pull rod 12, and a spring 14 is fixedly connected between the limiting plate 13 and the mounting plate 11. The silicon steel sheet 5 set in the mounting ring 4 has high magnetic permeability and can effectively guide the magnetic field, making the magnetic field more concentrated at the bottom of the pot 18 and reducing magnetic field leakage. The surrounding space is shielded by the magnetic properties of the induction cooker, which forms a magnetic shield to suppress the outward diffusion of the magnetic field and reduce magnetic leakage. Therefore, when the induction cooker is in use, the part of the magnetic field that leaks to the surroundings can be concentrated and guided to the cookware 18, thereby making the cookware 18 heat up more efficiently and preventing magnetic leakage to reduce energy consumption. This makes the induction cooker more efficient and energy-saving. At the same time, the silicon steel sheets 5 and the insulating plate 6 are staggered, that is, the silicon steel sheets 5 are insulated from each other by the insulating plate 6. By stacking multiple silicon steel sheets 5, a more continuous magnetic circuit can be formed, which improves the overall permeability and thus enhances the magnetic field strength. As a conductor, the silicon steel sheet 5 will also generate eddy current losses in the alternating magnetic field. The insulating plate 6 insulates the silicon steel sheets 5 from each other, which can increase the resistance between the silicon steel sheets 5 and reduce eddy current losses. This can prevent the phenomenon of decreased permeability caused by heat generated by eddy currents between the silicon steel sheets 5.
[0027] like Figures 3 to 6As shown, specifically, the mounting ring 4 has an air inlet 15, which is connected to the air duct 8. The air inlet 15 is located at the top of the cooling fan 3. The furnace body 1 has a heat dissipation vent 16 and an air circulation vent 17, with the air circulation vent 17 located at the bottom of the cooling fan 3. The cooling fan 3 in the induction cooker will start when the induction cooker is used. The cooling fan 3 will enter the air through the air circulation vent 17 to generate cooling air. The cooling air will enter the air duct 8 through the air inlet 15 and flow along the air duct 8. Then, the air in the air duct 8 will be discharged outward through the exhaust hole 9. When the air passes through the air duct 8 in the stacked layer 7, it can carry away the heat, thereby cooling the stacked layer 7, that is, cooling the silicon steel sheet 5, maintaining a normal temperature, and keeping its magnetic permeability within the normal range. At the same time, the hot air in the furnace body 1 can pass through the air duct 9. The heat dissipation vent 16 discharges outwards. When replacing the silicon steel sheet 5 or the insulating plate 6 in the mounting ring 4, remove the mounting ring 4, pull the lever 12 to drive the limiting plate 13, and the spring 14 will contract under force to generate a reaction force, thereby canceling the limiting effect of the limiting plate 13 on the stacked layer 7. Then, the silicon steel sheet 5 and the insulating plate 6 in the mounting ring 4 can be taken out. The new silicon steel sheet 5 and the insulating plate 6 are gradually placed in the mounting ring 4, so that the limiting post 10 penetrates the silicon steel sheet 5 and the insulating plate 6, thereby placing the silicon steel sheet 5 and the insulating plate 6 into the mounting ring 4 in the correct position. This allows the stacked layer 7 composed of the silicon steel sheet 5 and the insulating plate 6 to form the air channel 8 and the exhaust hole 9. The air channel 8 and the exhaust hole 9 are formed by processing individual silicon steel sheets 5 and insulating plates 6, which are then stacked to form the stacked layer 7.
[0028] like Figures 1 to 2 As shown, specifically, a pot 18 is provided at the top of the furnace body 1. A heat insulation plate 19 is provided on the outer side of the pot 18 to prevent heat loss from the pot 18. The heat insulation plate 19 is attached to the edge of the opening of the pot 18. A fixing plate 20 is fixedly connected to the heat insulation plate 19. The fixing plate 20 is provided with fixing bolts 21, and the furnace body 1 is provided with screw holes that are compatible with the fixing bolts 21. When the pot 18 is in use, heat is generated on the outer surface of the pot 18. This heat is transferred through the bottom of the pot 18, and the heat generated on the outer surface is dissipated into the air. The setting of the heat insulation plate 19 ensures that the dissipated heat is contained within the heat insulation plate. The heat insulation plate 19 is positioned between the heat insulation plate 19 and the outer surface of the cookware 18, preventing further heat dissipation and reducing heat loss. The dissipated heat is located between the heat insulation plate 19 and the outer surface of the cookware 18, i.e., around the cookware 18, and can continue to provide heat to the cookware 18, preventing excessive heat loss. Furthermore, the heat insulation plate 19 is fixed to the furnace body 1 by the fixing plate 20 and the fixing bolts 21, thereby fixing and limiting the heat insulation plate 19, and thus limiting the cookware 18. This prevents it from frequently shifting during cooking or other operations, which would lead to a decrease in magnetic field coupling efficiency, an increase in magnetic leakage, and affect the uniformity of heating.
